guest participant contact info security / celebrity attendee hypothetical

If a notable public figure attends a Zoom as a guest speaker to a larger corporate Zoom conference and has their own direct link to the meeting / are there any dangers to having their underlying contact info exposed to the 'civilian' attendees?  I presume the attendance functionality for owners/admins would be able to maybe capture that but ... for the general attendees, they're just seeing that Display Name in Zoom?

No way to reverse engineer and 'discover' that person's email address?  (celebrity stalker prevention strategy)
